XRD and EPMA

Improve your process understanding with fast, accurate and reliable micro beam analyses of your mineral samples.  

JKTech provides process improvement solutions based on the detailed mineral characterisation results provided by X-ray diffraction (XRD) and electron probe microanalysis (EPMA).

X-ray Diffraction (XRD) 
XRD uses the unique x-ray fingerprint of each mineral to identify and quantify its presence in a powdered sample of rock, ore, plant feed, concentrate or tailing sample. The JKTech XRD Facility is centred on a PANalytical X’PERT MPD PRO instrument equipped with PANalytical’s HighScore Plus advanced acquisition and data processing software. The facility offers three modes of analysis:
 
  • Qualitative Identification - mineral present
  • Semi-Quantitative analysis - identification and estimation of major/minor/trace components
  • Quantification of mineral species present - Rietveld quantification

Electron Probe Microanalysis (EPMA)
Electron microprobe analysis offers a range of microchemical analysis capabilities for mineral characterisation. Accurate and precise chemical quantification of major and minor elements to better than 0.03wt% is routine using spot analysis mode down to 1um in size. The JKTech EPMA Facility uses a 4-spectrometer CAMECA SX50 microprobe supported by SAMx data acquisition and processing software suite. Mineral characterisation applications of EPMA data include:

  • Accurate major and minor element numerical modelling
  • Deleterious element location and quantification
  • Minor to trace level element distribution and quantification
  • Element distribution mapping
 
Sample Requirements:
Samples for XRD analysis may be submitted in rock or pre-powdered form. Laboratory Services can crush rock samples specifically for XRD (and assay purposes) if required. 
 
Download the Sample Transmission Forms, which include Sample Hazard Advice Form, and Quarantine Declaration Form.  A completed Sample Hazard Advice Form must accompany every sample shipped to JKTech.  In addition, a Quarantine Declaration Form must be completed for every sample originating from outside Australia.
 
Key Benefits: 

XRD:

  • Rapid and reliable bulk mineralogy
  • Reliable mineral identification
  • Increase sample efficiency cluster analysis

EPMA:

  • Trace elements information
  • Detailed deleterious mineral informaton
